Meta-analyses of morbid obesity for CTNNBL1 rs6013029 and rs6020846. Estimated odds ratios (OR) [95% CI] for morbid obesity for minor allele carriers of CTNNBL1 rs6013029 and rs6020846, in combined analyses of the present, and a previous study . No heterogeneity between the two studies was observed (p = 0.5). The study by Liu et al.  included 2,669 lean controls and 877 morbidly obese cases for both variants and the present study included 5,190 controls and 399 cases for rs6013029 and 5,188 controls and 394 cases for rs6020846.
